How do I calculate Volume

[ra4u2nv 10+ year member]

How do I calculate the volume on a custom fiberglass box I made. It is my first box and I want to know if I can put 1 or 2 10" subs. It was molded in the car and has all types of grooves so how can I know the internal volume on this enclosure.

thanks

Ive also heard of using packaging peanuts to measure the volume of a fiberglass box

water is still way more accurate, but you wouldnt be far off with packing peanuts. water will also show any unsealed parts in the enclosure.

wont the water ruin the mdf baffle though? i heard when mdf gets wet it is trash.

I built my fibreglass box a while ago wanting to port it....but I won't do it unless I know my absolute volume...problem is half wood, half fibreglass...So I could'nt fill er with water...don't know what the hell packaging peanuts are either???...any other ideas...cause I want to port it

if by the baffle, you mean the mdf rings, a coat or two of resin will seal it right up.
